Vintage Mortise Lock Service in Selwyn
The old skeleton key still fits the keyhole, but it now needs a jiggle, a lean on the door and a little luck before the bolt moves. Last week it took three tries.
Vintage Mortise Lock Service
In plain words
Interior doors are as much a part of this work as the entry. Bedroom, bathroom and closet doors in an older home usually carry a lighter mortise latch with a privacy turn button, and after decades without lubrication they stop catching or the turn button seizes. These small cases are short jobs on the bench: a clean, a spring, a new turn button spindle where the old one has sheared. Sets of interior locks are often serviced in one visit, and a bit key can be cut that operates all of them, which is how they were originally supplied when the house was built.
How the visit goesYou bought a house with its original hardware and a bag of loose keys. Some open interior doors, some fit nothing, and the front door lock has a keyhole shaped for a key you do not have. You would like the original lock kept and made to work.

How the visit goes
Which keys exist and who has them
The locksmith asks to see every key that goes with the door: the one that works, the ones that used to, and the bag of loose bit keys that came with the house. A worn original is still the most useful pattern for a new key, and a bent one explains why the lock has become temperamental. For a cylinder lock, a lost or stolen key is a reason to rekey while the case is out, and a key that only a former occupant holds is worth retiring. The count of keys wanted afterwards is settled now too, so the spares are cut while the lock is on the bench rather than on a return visit.
Taking the lock out without marking the door
Removal is done in a set order so nothing is forced. The knob set screws are backed off and the knobs and spindle drawn out, then the escutcheons are lifted away, their screw positions photographed for reassembly. On a cylinder lock, the small set screw in the faceplate is released and the cylinder is unthreaded from the case. The faceplate screws come out, and the case is eased from its pocket with a gentle rock, never a pry bar, because the wood at the edge of an old door is thin. Everything that comes off is bagged and labelled, and the pocket is looked at while it is empty.
Watching the door through the seasons
The lock is aligned to the door as it hangs today, and a solid wood door in an older home will move again. Through a humid summer it swells, through the heating season it shrinks, and each year the hinges settle a fraction. Twice a year, close the door and try the latch and bolt; if either has started to scrape or needs the door lifted, the strike wants a small adjustment or the hinge screws want snugging, which is a five-minute job. Doing that early keeps the rebuilt case from being strained, and it is the single habit that makes a vintage lock last another few decades without fuss.

What affects the quote
Same fees day, night or weekend
1Parts that must be ordered
A reproduction case or an unusual cylinder size may have to be ordered to measurement, which means a second visit to fit it. The quote separates the first visit from the return.
2Number of locks in the visit
One entry lock is the simplest case. A whole floor of interior latches, or the front and back doors together, is a longer visit, and each case is quoted on its own so the total is easy to follow.
3Missing or mismatched trim
Sourcing a knob, escutcheon or thumb-turn to match the survivors, from salvage or reproduction stock, is quoted as parts plus the search. Reusing your own trim from another door avoids that line.
Vintage Mortise Lock Service: questions
What if the case is too worn to repair?
Then a replacement case goes into the existing pocket. Reproduction mortise cases are made in the common vintage sizes and backsets, and a modern mortise case with a cylinder fits many old pockets with minor trimming. The locksmith measures the case height, depth, backset and trim spacing before ordering, aiming for the new case to drop in with the original knobs and plates going back on, though a small pocket trim or fixing change is sometimes needed. Cutting the door for a different kind of lock is the last choice.
Can my interior doors be serviced too, and can one key work all of them?
Usually yes to the first, and to the second once the locksmith checks the locks. Interior mortise latches with privacy turn buttons are lighter versions of the entry lock and respond to the same clean and re-spring. Interior locks in a house were sometimes supplied to one bit key, and where the key sections, warding and levers actually match, the locksmith can restore that arrangement so a single key opens several bedroom and bathroom doors. It is a practical thing to have when a child locks a bathroom from inside.
Why does the deadbolt scrape or need a shove to throw?
Two causes cover most cases. Either paint has built up on the faceplate, the bolt or the strike so the bolt drags across it, or the door has dropped so the bolt is entering the strike pocket at an angle and rubbing its edge. Occasionally a bent deadbolt lever inside the case adds friction. Cleaning the paint back, adjusting the strike and checking the lever all happen as part of the service.
